Bug in getState and getStateV2 #5440
Comments
Found the error that is actually getting thrown:
|
It's really weird to see this error |
Here is a copy of the full stack trace and a screenshot. Was running for almost 13 min and then threw the error. Had super high cpu till it crashed so wondering if it was a single state transition (in the May-01 22:03:31.340[rest] error: Req req-8 getState error Validator indices must not be empty

You should dump to disk the state that this code path claims has no active validators to take a deeper look after the fact |

Serialized state that was saved in ssz format. |
@matthewkeil I'm not able to deserialize the downloaded state, could you give it a try? Error: Offset out of bounds 1690959926 > 6729301
at readVariableOffsets (/Users/tuyennguyen/Projects/lodestar/node_modules/@chainsafe/ssz/src/type/container.ts:451:13) maybe you could try |

Let's archive this issue for now and revisit latter |
Leaving a breadcrumb here. When the db attempts to pull the nearest state to regen from it eventually attempts to pull and the repo returns null when it does not find it cached here |
I think #6033 will tackle this |

Describe the bug
I was attempting to resolve ticket #5409 and the epoch state transitions but cannot pull the historical state. I believe the system is timing out when attempting to recreate the state through state transition.
Attempted to pull state via
slot
and0x
prefixed hexstateRoot
but was unable to pull the data. The named stateshead
,finalized
etc work fine but older states to not get returned.Expected behavior
curl -H "Accept: application/octet-stream" https://lodestar-mainnet.chainsafe.io/eth/v2/debug/beacon/states/6123583 -o state_mainnet_6123583.ssz
should output the state to disk in SSZ format.Steps to Reproduce
run:
curl -H "Accept: application/octet-stream" https://lodestar-mainnet.chainsafe.io/eth/v2/debug/beacon/states/6123583 -o state_mainnet_6123583.ssz
returns: 504
run:
curl -H "Accept: application/octet-stream" https://lodestar-mainnet.chainsafe.io/eth/v2/debug/beacon/states/0xadd30839a0a9bb6705edf4b0ee08b160af85ecc4e7ffc7ec0198575e339397f0 -o state_mainnet_6123583.ssz
returns: 404 or 504 depending on the root used
